Wow, thanks for reaching out and responding everyone. I appreciate it!
I should point out though that this tune I was inquiring about isn’t a song you’d find somewhere - I’m pretty sure it was something Qantas had made itself. It only lasted for a few seconds and usually played in between songs. If anyone has had any luck with Qantas releasing things like this then let me know how you managed to do it as I feel it might be the only way.
